Key Parameters

Substitute Part Grouping Explanation

The SI2435-D-FTR has one direct substitute: SI2435-E-FTR. Substitution eligibility is determined by the following critical parameters:

• Data Format & Protocol: Both parts implement V.34 modem standard
• Data Rate: Both support 33.6 kbps operation
• Supply Voltage: Both operate at 3.3V
• Package Type: Both use 24-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width)
• Electrical Characteristics: Identical MSL rating (3, 168 Hours)
• Regulatory Compliance: Matching ECCN and HTSUS classifications
• Base Product Number: Both derive from SI2435 series

The primary distinction between these parts is product status and packaging format, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The SI2435-E-FTR is the direct substitute for the SI2435-D-FTR. Both parts are electrically and mechanically identical across all functional parameters. The SI2435-E-FTR is currently in active production status, whereas the SI2435-D-FTR is obsolete. For new designs or component replenishment, the SI2435-E-FTR should be selected based on product availability and active manufacturing status. The SI2435-E-FTR is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume surface mount assembly operations. Both parts maintain identical regulatory compliance classifications and moisture sensitivity specifications.
